Saudi Arabian Desert |
||||||
 |
||||||
|
||||||
| Saudi Arabia may be an arid country, but when rain falls it tends to come in violent torrents that can cause considerable erosion. This landscape is created by the rainwater carving out deep channels, or wadis, in the earth and the rocks being weathered by wind and dramatic daily temperature changes. The softer rock has been worn away into sand while the harder rock remains and sharply rises from the deeply eroded tableland. | ||||||
